A few users of the XL_STAR board shared their concerns as and when they found some components on the board were running at high temperature.
A quick look at the board in its various modes of operation suggested that we needed to cover the following:
When using the XL_STAR for USB device development, via J1 (the USB connector on the top side of the XL_STAR), the XL_STAR
must be powered via a USB cable connected to J6 (the USB connector on the underside of the XL_STAR) before a USB cable is connected to J1.
If USB cables are not connected in this order the USB regulator on U1 will be overloaded and permanent damage to U1 may occur.
This operational requirement was ommitted from the initial release of the documentation.
The updated user guide is now available, see the attached documents.
